There is a spray called "Kleen Screen" that you can spray on a microfiber cloth and clean the screen with it. It works well on the Pre (originally got it for my laptop screen several years ago - works well on this, too).

You can also get a LensPen made for digital screens. One side has a soft brush to get dust off (works great to get the dust out of the Pre's phone speaker and between the keys on the Pre's keyboard) and then the other side has a special tip to get the oil and such off. It is very similar (if not exactly the same) to the LensPens for camera lenses. Oh - and there is also a teeny-tiny LensPen made just for cell phone camera lenses! They both work well (as do LensPens for camera lenses - I use them on all my DSLR lenses ... and I also use the digital screen one on my DSLR's LCD screen).

I use steel wool for the screen, and to clean the keyboard, I open my pre and submerge the keyboard in hydrochloric acid (make sure to swish it around a little), then dip it in some water, wipe dry and it's good to go!

You should try 400 grit sandpaper, then follow it up with 1000 grit. Works great and keeps the fingerprints off.

If I go that route, i use the 1000 grit. After you do that, you can't see ANY fingerprints! Not only does it get rid of the ones already there, but you will also never see another fingerprint on your pre again. It's a win-win.
